Ulmus americana (American Elm)

American Elm is a large, handsome vase-shaped tree with a symmetrical crown. Fall color is yellow. It is mostly found along moist bottomland sites but can also be seen in upland areas with good soils.

American Elm has shallow roots with a deep tap root that resists movement from floodwater, making this species valuable for preventing soil erosion. It is susceptible to Dutch elm disease.

Planting Instructions: If the tree is buried too deep in the container, remove excess soil to uncover root collar. Loosen exterior roots gently. Place the tree so that the root collar sits a bit above the ground level since the soil will settle. Backfill using soil that was dug out. Do not add any soil to the top of the root ball. Pack the loose soil with your hands to avoid creating air pockets. Add mulch at least 3-5 inches away from the tree trunk. Water deeply.
